The bar chart illustrates the age of women in Australia who were having a baby over the period given.
Overall, it is evident that three types of age groups show the downward trend, while others show the upward trend until the end of years. Moreover, we can be seen that women at the age of 19-24 were the highest percentage in 1966.
Examining the details, the number of women who are 19-24 years old recorded the highest value with more than 60% until the percentage started to decline to 38%. Likewise, the figure for women aged under 19 dramatically decreased from around 34% to 20% and about 11% for the whole period. By 1986, this pattern had shifted, with 25-30 becoming the most common age group.
In 2006, women giving birth at the ages 30-34 became the largest group, and the number for women aged 34-39 and over 40 continued to grow.
